Andy Murray criticises parts of his game after his latest early exit in Madrid

Andy Murray conceded lots of parts of his game "weren't particularly good" after his latest early exit in Madrid.

If 2016 was one of the best of the world number one's career, 2017 is proving to be the opposite.

Injury has bothered him and form deserted him across the first four and a half months of the year and there was little to smile about as Borna Coric dumped him out of the Mutua Madrid Open.

Coric, 59th in the world, won 6-3 6-3 as the Scot's desperate pursuit of consistency went on.

"There were a lot of things that weren't particularly good," Murray told BBC Sport.

"I made a lot of unforced errors and I also didn't find any way to make it a more competitive match, so that's the most disappointing thing.

"Things can change fast but you need to find exactly what it is that is going wrong and how you're going to fix that and commit to it. And if I do that, I'm sure I can turn it round."

Murray's form is in stark contrast to this point last year when, then the perennial number two in the rankings behind Novak Djokovic, he embarked on a phenomenal seven-month run to propel himself to the top of the rankings pile.

He could now have to repeat something like that eye-watering effort to stay there but it is clear he is still finding his way after his elbow injury.
